The Lowdown

Right now, we’re looking at a patchy stretch ahead. The first few days are pretty average, with wave heights hovering around the 3ft mark and mostly southerly energy. It’s not terrible, but it’s not firing. Then there’s a real lull mid-week, and things go quiet for a bit before a late pulse tries to get going. The standout window is shaping up to be Friday the 25th – that’s the one to circle.

Monday (14th) and Tuesday (15th):
Jaconé (Rio de Janeiro) has some clean mornings on Monday – around 4ft to 4ft from the south, with a light offshore breeze. It’s surfable but nothing to write home about. The combined energy is weak to moderate at 228, then 379. Tuesday drops off – onshores kick in, the swell fades to under 3ft, and it turns messy. Not worth the paddle.

Wednesday (16th) to Thursday (17th):
Wednesday is poor – onshore wind and junky conditions. Thursday sees a slight bump in size (5ft to 6ft) with the period stretching out to 13 seconds, and the wind turns cross-off. It’s cleaner, but the tide questions linger. Energy jumps to 752, then 1223 – that’s moderate to strong, but still not quite clicking.

Friday (18th):
Best of the first week. Morning has 6ft from the south, 12-second period, ENE offshore at 25 km/h. That’s a proper clean, lined-up set of waves. The combined energy is 846 – strong. Afternoon drops off a bit with more wind. Still, Friday morning is your pick if you can only get out once early.

Saturday (19th) to Sunday (20th):
Saturday drops back to 4ft to 5ft, and the period shortens to 6-7 seconds – that’s windswell, lumpy and less punchy. Offshore winds keep it clean-ish, but the energy is waning (344-465). Sunday is similar, 5ft to 6ft from the east, still short period. It’s surfable but definitely a step down.

Monday (21st) and Tuesday (22nd):
A real lull. Monday has small 4ft to 4ft waves, period drops to 8 seconds, energy down to 214. Tuesday bottoms out – 3ft and then 3ft, poor conditions. This is the gap. If you blink, you’ll miss it. No real swell to speak of for a good three to four days.

Wednesday (23rd) and Thursday (24th):
Wednesday morning has a small bump to 4ft from the east, but the afternoon is a washout with onshore winds and building to 5ft – not worth it. Thursday is the absolute flattest – 2ft to 3ft, glassy but tiny. The only spot of light is Thursday afternoon – 3ft from the south, 14-second period, but it’s marginal.

Friday (25th):
Here’s your standout. Morning has 5ft from the SSW, 11-second period, ENE offshore at 10 km/h, glassy and clean. Combined energy is 615 – solid. This is the best surf of the entire run. The water temp is 73°, about normal for the time of year. Crowds are possible, but with this kind of quality, it’s worth sharing.

Saturday (26th) and Sunday (27th):
Saturday fades fast – 3ft in the morning, then 3ft in the afternoon. Still clean, but small. Sunday is tiny – 2ft and 1ft, glassy but very ordinary. The swell has completely run out of puff.

Monday (28th) onwards:
Monday blows up with 6ft from the south in the afternoon, but it’s onshore and messy – poor quality. Tuesday has 4ft from the SSW, but winds are cross-shore and bumpy. Nothing here is worth the drive.

Bottom line:
Friday the 25th morning at Jaconé is the clear winner – clean 5ft from the south-southwest, offshore breeze, and decent energy. That’s your day. The rest is mostly average or below, with a real flat spell mid-period. If you can’t make Friday, the next best is Friday the 18th morning, but it’s not as polished. As for beginners – anything over 5ft is pushing it, and Friday is right at that mark. Experts will lap it up. The long-period south swells around the 14th and 24th are better for points and reefs, but Jaconé is exposed, so it’ll handle it fine.

Stay stoked, and don’t sleep on that 25th.

Information about the Jaconé Surf forecast

The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.

Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
